Docker Extensions: Using and Building Them

🙌 My next course is coming soon! I've opened the waitlist for those wanting to go deep in GitHub Actions for DevOps and AI automation in 2025. I'm so thrilled to announce this course. The waitlist allows you to quickly sign up for some content updates, discounts, and more as I finish building the course. https://learn.bretfisher.com/waitlist🍾Bret is joined by Guillaume Tardif and Felipe Cruz of Docker Inc. for a deep dive into Docker extensions.Docker Extensions are a favorite new feature. Guillaume and Felipe are both engineers at Docker and they walk us through how extensions came about, how to install them, and how to submit them to the marketplace.By the time Docker released extensions at DockerCon in May 2022, there were already a dozen solid extensions, including a disk manager, log explorer, and other third-party tools like Portainer, Snyk, and Anchor. Docker extensions will be most helpful to people who use Docker Desktop.Streamed live on YouTube on June 16, 2022.Unedited live recording of this show on YouTube (Ep #174).
